Question

Calculate the volume of 1 M NaOH needed to prepare 10.0 ml of a 0.10 M solution.

Answer 1

Using the known concentration and desired volume, we can calculate the volume of NaOH needed:

volume = 0.10 M x 0.010 L = 0.0010 moles .To prepare a 0.10 M solution of NaOH, you will need a volume of 0.0010 moles of NaOH.

Step-by-step explanation:

To calculate the volume of 1 M NaOH needed to prepare a 0.10 M solution, we can use the equation:

moles = concentration x volume

In this case, the concentration is 0.10 M and the desired volume is 10.0 ml (0.010 L). Rearranging the equation, we have:

volume = moles / concentration

Using the known concentration and desired volume, we can calculate the volume of NaOH needed:

volume = 0.10 M x 0.010 L = 0.0010 moles

Answer 2

Answer is: volume of 1 M NaOH is 1 ml.
c₁(NaOH) = 1 M.
V₂(NaOH) = 10 ml.
c₂(NaOH) = 0,1 M.
V₁(NaOH) = ?
c₁ - original concentration of the solution, before it gets diluted.
c₂ - final concentration of the solution, after dilution.
V₁ - volume to be diluted.
V₂ - final volume after dilution.
c₁ · V₁ = c₂ · V₂.
V₁(NaOH) = c₂ · V₂ ÷ c₁.
V₁(NaOH) = 0,1 M · 10 ml ÷ 1 M.
V₁(NaOH) = 1 ml.
